There's many things to do when releasing a song. And I really ain't have the spoons for them all. 

I need to upload to Bandcamp

Upload to jam.coop

Register the song with SoundExchange, the MLC and Raap I believe. 

I need to add it to Genius 

Make a press release 

Take press photos 

Send to bloggers and music people and radio stations 

Blah blah blah blah 

Make short form videos 

So on and so forth with promo and marketing 

Still there's more clarity here on the music side than the writing side lmao.
